-Subject: rt: Drop mutex_disable() on !DEBUG configs and the GPL suffix from
- export symbol
-
-Alex Goins reported that mutex_destroy() on RT will force a GPL only symbol
-which won't link and therefore fail on a non-GPL kernel module.
-This does not happen on !RT and is a regression on RT which we would like to
-avoid.
-I try here the easy thing and to not use rt_mutex_destroy() if
-CONFIG_DEBUG_MUTEXES is not enabled. This will still break for the DEBUG
-configs so instead of adding a wrapper around rt_mutex_destroy() (which we have
-for rt_mutex_lock() for instance) I am simply dropping the GPL part from the
-export.
